• Abstract:
  Traffic noise abatement in mountain corridors can be difficult because traditional roadside barriers may be ineffective ; due to topography or may not fit the setting. This study examined current best practices from around the world to gather ; concepts for mitigating traffic noise in mountain corridors in Colorado. A literature review of prospective noise ; abatement actions found that noise barriers are the most effective direct noise abatement measure, although quieter ; pavements could have an important supporting role. The literature review was followed by computerized traffic noise ; modeling of promising candidate barrier concepts. Several noise barriers were evaluated through modeling at two areas ; along the I-70 corridor using the Nord2000 Road prediction method. Each of the barriers was found to be effective in ; some or many situations; the largest, most imposing barrier (galleries) showed the most potential for reducing traffic ; noise at locations above the elevation of the highway. Continued use of noise barriers as a primary abatement ; mechanism was recommended. Consideration of quieter default pavement types was recommended to lower general ; traffic noise levels in support of environmental stewardship goals.
